The influence of ultradisperse additives of β-sialon and molybdenum disulfide on the interfacial boundary conditions of nitrile rubber containing 17–20% of acrylonitrile (SKN-18) and ultrahigh molecular-weight polyethylene (UHMWPE) is studied. The additives were introduced into the nonpolar UHMWPE, and then the modified composition was introduced into a crude rubber stock based on SKN-18. X-ray diffractometry, electron microscopy, and dynamic testing methods were used for studying the phase and supramolecular structure of the composition. A complex of physical and mechanical tests including the study of the wear and oil and cold resistance characteristics of the elastomeric compositions were carried out. It is shown that the use of ultradisperse additives allows us to improve the interaction at the SKN-18/UHMWPE interface and the operating properties of the materials.
